Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum cleaner,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of jetting a fluid while compressing dust collected in a dust collector to solidify compressed dust.

A vacuum cleaner is an electric device that can remove dust and other foreign substances on the floor or furniture of a building by using a mechanism that sucks outside air using vacuum pressure.

Such a vacuum cleaner is divided into a canister type in which a main body and a suction nozzle are separated from each other and connected to a predetermined pipe, and an up-right type in which a suction nozzle and a main body are provided together.

Generally, the vacuum cleaner includes a suction nozzle, a dust separator for separating air and foreign substances introduced from the suction nozzle by a cyclone principle, and a dust collecting unit for collecting dust and other foreign substances connected to the foreign matter discharging unit of the dust separator. A vacuum motor connected to the air discharging unit of the dust separating apparatus to form a vacuum, and a filter connected to the discharging unit of the vacuum pump for filtering the air flowing out to the outside.

When the user operates the vacuum cleaner under such a configuration, air and foreign matter passing through the suction nozzle rotate in the dust separator, while foreign matter having a large mass rotates the inner circumferential surface of the dust separator by the centrifugal force and then flows into the dust collector.

The cleaned air is discharged to the outside through the motor and the filter.

However, when dust or other foreign matter accumulates in the dust collecting apparatus, the dust is scattered inside due to its light mass, and there is also a problem that even when the dust collecting apparatus is taken out and the foreign matter in the dust collecting apparatus is discarded, the dust is scattered.

The present invention can reduce the volume of dust by compressing the dust collected in the dust collecting apparatus, and also allows the compressed dust to be mixed with the fluid to keep the compressed dust in a solid state so that the inside of the dust collecting apparatus can be easily cleaned The object of the present invention is to provide a vacuum cleaner.

According to an aspect of the present invention, there is provided a dust collecting apparatus comprising: a dust separating apparatus provided in a main body; a dust collecting apparatus connected to the dust separating apparatus; A dust compressing part movably provided in the dust collecting device and selectively compressing dust by applying pressure to the dust in the dust collecting device; A fluid receiving portion provided in the dust collecting device or the main body to receive a fluid for solidifying dust, and a fluid outlet portion connected to the fluid receiving portion and selectively opened when dust is received in the dust collecting device, And a fluid discharging portion provided in the direction of dust, wherein the fluid discharging portion includes an opening / closing member provided inside the opening and closing member for controlling the flow of the fluid, wherein the opening and closing member is deformed by an external force, The vacuum cleaner is guided to be discharged to the outside.

According to the present invention, since the dust compressing unit is expanded or contracted in the inside of the dust collecting apparatus and moves up and down, dust can be compressed easily to minimize the dust volume.

The operation of the dust compressing portion is made by selectively connecting the dust compressing portion and the portion having a difference from the pressure inside the dust collecting device. Therefore, there is an advantage that the user does not need to separately perform the operation for compressing the dust.

Further, since the fluid for dust solidification is injected in the compressed dust direction at the same time as the dust compression action, there is an advantage that dust is not blown when the dust is removed from the dust collecting apparatus.

Since the fluid discharge portion and the fluid receiving portion for providing the fluid for dust solidification are mounted on the dust compression portion, the size of the body is smaller in terms of not requiring a space for installing the fluid discharge portion and the fluid receiving portion separately in the body There is also an advantage.

[ It is preferable to provide the tapered shape at an upper portion of the first tapered portion 632 so that the width of the tapered portion becomes smaller toward the upper portion.

When the moving member 630 is inserted into the opening and closing member 620, the rim provided at the upper end of the upper body portion 632 comes into contact with the inner surface of the slanting portion 622.

Here, the opening and closing member 620 is made of silicone or rubber and is deformed when an external force is applied.

Accordingly, when the movable member 630 does not move upwards and the external force is not directly applied to the opening / closing member 620, the slit portion 624 is closed and the fluid can not pass through the slit portion 624.

However, when the opening and closing member 520 is deformed due to an external force in the direction of the inclined portion 621 due to the upward movement of the movable member 630, the slit portion 524 is opened, have.

A force transmitting device 550 is provided below the moving member 630 to cause the moving member 620 to move upward to open the slit portion 624 of the opening and closing member 620.

The sealing member 554 serves as a seal to prevent fluid from penetrating the force transmitting device 550.

The force transmitting device 550 includes a cover member 555 that receives the moving plate 551, the force transmitting member 552 and the guide member 553 and prevents them from being exposed to the outside, .

The rim of the cover member 555 is fixed to the lower surface of the mounting plate 501 and a fixing member 556 of a toric shape is fixed to the rim of the cover member 555 for fixing the cover member 555 Respectively.

The cover member 555 is preferably made of an elastic material.

Therefore, when the lower end of the dust compression unit 500 comes into contact with the dust to be compressed due to the downward movement of the dust compression unit 500, the dust lump is compressed, and the lower surface of the cover member 555 .

When the dust lump is compressed, it has a predetermined strength. When the dust compression unit 530 further moves downward in a state of being in contact with the cover member 555, by the reaction of compression against the dust lump, The force is transmitted from the cover member 555 toward the cover member 555.

That is, a lump of dust presses the cover member 555.

By this pressing, the shape of the cover member 555 is deformed, whereby the moving plate 551 and the force transmitting member 552 are moved upward.

The discharge nozzle 605 is provided on the lower surface of the mounting plate 601 so as to extend downward to guide the fluid to be discharged downward.

The fact that dust compression is generated by the dust compressing unit 100 and the pressing force is transmitted from the compressed dust back to the fluid discharging unit 500 means that the dust is supplied by the fluid discharging unit 500 Which means that the fluid is discharged.

That is, the dust is mechanically sensed by the fluid discharge part 500 and the fluid is discharged.

If there is a small amount of dust so as not to touch the fluid discharge part 500, the fluid will not be discharged from the fluid discharge part 500 even if the dust compression part 100 compresses.

As a result, the fluid discharging part 500 is selectively opened in the dust collecting device 100 depending on whether the dust is pressurized from the dust, thereby providing the fluid in the dust direction.

The principle of fluid discharge according to such dust detection is commonly applied to other embodiments.

As shown in FIG. 9, the opening / closing member 620 is provided inside the inflow passage 614.

The projecting portion 626 is brought into contact with the inner wall surface of the accommodating portion 602 so that the opening and closing member 620 can be fixed without moving within the inflow conduit 614, .

When the receiving portion 602 and the receiving portion cover 603 are coupled by a predetermined fastening member (e.g., bolt, rivet, hook, or the like), the opening and closing member 620 is prevented from flowing.

The movable member 630 is disposed inside the opening / closing member 620 in a state where the opening / closing member 620 is fixed. As described above, the moving member 630 includes the lower body portion 631 and the upper body portion 632.

The lower end of the lower body part 631 is disposed on the sealing member 554 and the upper end of the upper body part 632 is in contact with the inner surface of the inclined part 622.

Since the width of the internal space of the opening and closing member 620 is formed to be wider than the width of the moving member 630, a clearance is formed around the moving member 630.

This clearance space is in communication with the discharge passage 604.

Therefore, when the moving member 630 rises and the slit portion 624 is opened, the fluid in the inflow passage 614 flows through the slit portion 624, the space around the moving member 630, The discharge passage 604, and the discharge nozzle 605, and is discharged to the outside of the fluid discharge portion 600.

Here, dust compression is generated by the dust compressing unit 100 and the pressing force is transmitted from the compressed dust back to the fluid discharging unit 500 because the fluid is discharged from the fluid discharging unit 600 to the dust discharging unit 600 Which means that the fluid is discharged.

That is, the dust is mechanically sensed by the fluid discharge part 600 and the fluid is discharged.

If there is a small amount of dust so as not to touch the fluid discharge part 600, the fluid will not be discharged from the fluid discharge part 600 even if the dust compression part 100 compresses.

10 is an exploded perspective view of a third embodiment of the fluid discharge part 600. FIG.

In the second embodiment, the opening / closing member 650 (see FIG. 8) 620 has a hollow cylinder shape. However, the opening / closing member 650 in the fluid discharging portion 600 according to the third embodiment may be a membrane or a plate And one or more slit portions 651 formed on the surface of the body portion 651.

The body portion 651 is preferably formed in a curved surface shape having a predetermined curvature, but may be in a planar state.

The opening and closing member 650 is also made of a resilient rubber or a silicone member, and is easily deformed when an external force is applied, and is easily restored to its original state when an external force is lost.

When the opening and closing member 650 is deformed, the slit portion 652 is opened by being opened between the slit portions 652, and when the slit portion 652 is restored to the state before the deformation, the slit portion 652 is closed again.

The movable member 630 is provided under the opening and closing member 650 and maintains a state where an external force can be applied to the opening and closing member 650 when a force is applied thereto.

The remaining configurations except for the above-described configuration are the same as those of the second embodiment shown in FIG. 8, so a detailed description thereof will be omitted.

11, the opening and closing member 650 is disposed in the inflow passage 614, and the rim thereof is fixed to the wall surface of the inflow passage 614. As shown in Fig.

The moving member 630 is composed of an upper body part 631 and a lower body part 632. The upper body part 631 is in contact with the upper surface of the sealing member 554 disposed below the upper body part 631, The upper edge of the lower body portion 632 comes into contact with the lower surface of the opening / closing member 650. [

Accordingly, when the force is transmitted to the moving member 630 by the force transmitting device 550, the moving member 630 performs the upward movement, thereby raising the opening / closing member 650 upward.

At this time, since the rim of the opening and closing member 650 is fixed, the central portion of the opening and closing member 650 rises so that the surface area increases, and the slit portion 652 can be opened accordingly.

The lower space of the opening / closing member 650 is in communication with the discharge passage 604, and the lower space of the opening / closing member 650 is larger than the width of the moving member 630, thereby forming a clearance space.

When the slit portion 652 is opened, the fluid in the inflow passage 614 sequentially passes through the slit portion 652, its clearance space, the discharge passage 604, and the discharge nozzle 605 And is discharged to the outside.

Operations of the remaining configurations other than those described above are the same as those of the second embodiment shown in FIG. 9, and thus description thereof will be omitted.

Hereinafter, the operation of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 12, when the vacuum motor 10 operates, dust and air sucked in the suction nozzle (not shown) flows into the dust separator 20.

Dust separated from the air by the cyclone principle flows into the dust collecting apparatus (30) inside the dust separating apparatus (20).

The air separated from the dust is sucked into the vacuum motor 10 through the filter device 50 and then discharged to the outside of the main body.

The dust introduced into the dust collecting apparatus 30 is collected under the dust collecting apparatus 30. At this time, the suction unit (low pressure unit) of the vacuum motor and the dust compressing unit 100 communicate with each other.

In this case, as shown in FIG. 13, the length of the dust compressing unit 100 is reduced, so that the lower portion of the dust compressing unit 100 is separated from the bottom surface of the dust collecting apparatus 30 by a predetermined distance It is separated.

Accordingly, the fluid outlet 500 (600) may also be spaced a predetermined distance from the bottom surface of the dust collecting apparatus.

Since the dust compressing unit 100 does not perform the function of compressing the dust when the size of the dust compressing unit 100 is reduced, a dust or a lump of dust presses the fluid discharging unit 500 (600) I never do that.

As shown in FIG. 14, in the first embodiment of the present invention, when the force transmitting device 550 does not press the opening / closing member 520, the opening / closing member 520 keeps its shape in an initial state .

The slit portion 524 is kept closed.

The fluid L introduced into the inflow passage 514 under the guidance of the guide tube 250 is guided by the flow passage portion 513 and the discharge passage 504 , And is maintained in the state of being accommodated in the inflow passage 514. [

15, in the second embodiment of the present invention, the force transmitting device 550 does not lift the moving member 630, so that the moving member 630 is urged against the opening and closing member 620 The opening / closing member 620 keeps its shape in the initial state.

The slit portion 624 is kept closed.

The fluid L introduced into the inflow passage 614 under the guidance of the guide pipe 250 is discharged to the discharge portion 625 of the open / close member 620, And can not move in the direction of the discharge passage 604, and is maintained in the state of being accommodated in the inflow passage 614.

16, in the third embodiment of the present invention, the force transmitting device 550 does not lift the moving member 630, so that the moving member 630 is pressed against the opening and closing member 650 The opening and closing member 650 keeps its shape in its initial state.

The slit portion 652 is kept closed.

The fluid L introduced into the inflow passage 614 under the guidance of the guide pipe 250 is discharged to the lower space of the opening and closing member 650 and the discharge It can not move in the direction of the flow path 604 and maintains the state accommodated in the inflow path 614.

17, the dust compression unit 100 and the discharge unit (not shown) of the vacuum motor 10 can be separated from each other by the switching device 400 in a state in which dust is collected to the dust collecting apparatus 30 The dust compressing unit 100 is expanded and the lower surface of the dust compressing unit 100 moves toward the bottom surface of the dust collecting apparatus 30. [

Accordingly, the fluid discharge part 500 (600) provided on the lower surface of the dust compressing part 100 compresses the dust and is pressed by the repulsive force of the compressed dust lump to discharge the fluid in the dust lump direction .

18, the bottom surface of the dust compressing unit 100 moves toward the bottom surface of the dust collecting apparatus 30, and when the collected dust D is pressed, the dusts are compressed.

Since the guide tube 250 is provided in the form of a coil, the height of the guide tube 250 is increased to continuously connect the fluid storage part 200 and the fluid discharge part 500 (600) And directs the fluid to the fluid outlet 500 (600).

At this time, the compressed dust D is in a lump shape to make contact with the fluid discharge portion 500 and presses the cover member 555 of the fluid discharge portion 500 (600).

This is because the dust particles D compressed by the principle of action and reaction also provide a repulsive force toward the fluid discharge portion 500 (600).

As shown in FIG. 19, in the first embodiment of the present invention, when the dust compressing portion (FIGS. 18 and 100) expands and the lower surface of the dust compressing portion 100 is pressed against dust, (D) contacts the cover member (555).

As the dust compaction unit 100 descends, the compressed dust lid D upwardly moves the cover member 555, and the moving plate 551 and the force transmitting member 552 move upward do.

The upper end of the upward force transmitting member 552 is in contact with the lower surface of the sealing member 554 and one surface of the opening and closing member 520 is in contact with the upper surface of the sealing member 554.

Accordingly, when the force transmitting member 552 moves upward, the sealing member 554 slightly rises so much that the opening and closing member 520 is deformed by the force.

When the opening / closing member 520 is deformed, the slit portion 524 opens and the fluid L received in the inflow passage 514 flows there.

The fluid L that has passed through the slit portion 524 enters the inside of the opening and closing member 520 and flows through the flow path portion 513a and dispersedly flows into the respective discharge flow paths 504.

The fluid L that has passed through the discharge passage 504 is discharged from the discharge nozzle 505, and then is injected into the compressed dust mass D.

The compressed dust particles D are solidified by mixing the fluid L and dust can be prevented from being blown thereafter when cleaning the dust collecting apparatus.

When the dust compression unit 100 is lifted and the contact state between the dust block D and the cover member 555 is released, the force pressing the opening / closing member 520 is released, 520 return to their original state.

14, the slit part 524 is closed again to block the fluid L from moving to the discharge pathway 504. As shown in FIG.

As shown in FIG. 20, in the second embodiment of the present invention, when the dust compressing portion (FIGS. 18 and 100) expands and the lower surface of the dust compressing portion 100 touches the dust to compress the dust, (D) contacts the cover member (555).

As the dust compaction unit 100 descends, the compressed dust lid D upwardly moves the cover member 555, and the moving plate 551 and the force transmitting member 552 move upward do.

The upper end of the upwardly moving force transmitting member 552 is in contact with the lower surface of the sealing member 554 and the lower end of the moving member 630 is in contact with the upper surface of the sealing member 554.

The upper end of the moving member 630 is in contact with the inside of the inclined surface 622 of the opening and closing member 620.

Accordingly, when the force transmitting member 552 moves upward, the sealing member 554 slightly rises so much that the moving member 620 also rises.

So that the opening and closing member 620 is deformed by the force of the moving member 620.

When the opening and closing member 620 is deformed, the slit portion 624 opens and the fluid L received in the inflow passage 614 flows there.

The fluid L that has passed through the slit portion 624 enters the inside of the opening and closing member 620 and passes through the discharging portion 625 of the opening and closing member 620, It flows.

The fluid L that has passed through the discharge passage 604 is discharged from the discharge nozzle 605 and is then injected into the compressed dust particles D. [

The compressed dust particles D are solidified by mixing the fluid L and dust can be prevented from being blown thereafter when cleaning the dust collecting apparatus.

On the other hand, when the dust compression unit 100 is lifted and the contact state between the dust block D and the cover member 555 is released, the force for pressing the opening / closing member 620 is released, 620 return to their original state.

15, the slit portion 624 is closed again to block the fluid L from moving to the discharge passage 604. As shown in FIG.

As shown in FIG. 21, in the third embodiment of the present invention, when the dust compressing portion (FIGS. 18 and 100) expands and the lower surface of the dust compressing portion 100 comes into contact with the dust to compress the dust, (D) contacts the cover member (555).

As the dust compaction unit 100 descends, the compressed dust lid D upwardly moves the cover member 555, and the moving plate 551 and the force transmitting member 552 move upward do.

The upper end of the upwardly moving force transmitting member 552 is in contact with the lower surface of the sealing member 554 and the lower end of the moving member 630 is in contact with the upper surface of the sealing member 554.

The upper end of the moving member 630 is in contact with the lower surface of the opening / closing member 650.

Accordingly, when the force transmitting member 552 moves upward, the sealing member 554 slightly rises so much that the moving member 620 also rises.

As a result, the opening / closing member 650 is urged by the moving member 620 so that the contact portion rises and deforms, and the surface area of the contact portion is increased to open the slit portion 652.

When the slit portion 652 is opened and opened, the fluid L received in the inflow passage 614 flows there.

The fluid L that has passed through the slit portion 652 passes through the lower space of the opening and closing member 650 and then flows into the respective discharge flow paths 604 in a dispersed manner.

The fluid L that has passed through the discharge passage 604 is discharged from the discharge nozzle 605 and is then injected into the compressed dust particles D. [

The compressed dust particles D are solidified by mixing the fluid L and dust can be prevented from being blown thereafter when cleaning the dust collecting apparatus.

When the dust compression unit 100 is lifted and the contact state between the dust block D and the cover member 555 is released, the force for pressing the opening / closing member 650 is released, 650 returns to its original state.

Thus, the slit portion 652 is closed again to block the fluid L from moving to the discharge passage 604 as shown in FIG.
